The Zenoah 31.8cc engine is specially designed for radio-controlled thermal cars . The heart of the engine is a newly developed crankshaft which is supported by larger bearings. The big-end bearing has been increased from 10 to 12 mm, the piston pin bearing has been renewed and enlarged from 8 to 9 mm, the crankshaft bearings have been increased from 28 to 32 mm! All this ensures better “Flow” in the engine, therefore much more power .
